Recent research published in the Journal of the International Society of Sports Nutrition reveals that daily creatine supplementation might assist middle-aged and older adults in maintaining lean muscle mass, improving strength, and supporting cognitive function. This holds true regardless of whether it is accompanied by exercise.
The Study
The 12-week study, conducted by Texas A&M University’s Exercise & Sport Nutrition Lab, involved 64 participants aged 45 to 65. They were divided into two groups: one with no exercise and another combining exercise with dietary interventions. Participants in each group were randomly assigned to consume either 10 grams of creatine monohydrate per day or a placebo.
“Creatine is a naturally occurring compound that aids cells in regenerating adenosine triphosphate (ATP), the main energy source for cellular activities in both muscles and brain tissue,” states the Cleveland Clinic.
Benefits of Creatine Monohydrate
Creatine monohydrate, a popular dietary supplement, assists muscles in producing quick energy for activities such as strength training. The study found that this supplementation contributed to increased lean muscle mass and strength in middle-aged and older adults.
Sarcopenia, the loss of muscle mass and strength associated with aging, can be accelerated by certain diets. However, the study indicated that creatine monohydrate helps mitigate muscle loss.
Exercise and Diet Intervention
Adding creatine to an exercise and diet program led to more significant body fat reductions, better lean body mass preservation, and notable enhancements in strength compared to a placebo. Even participants without exercise or dietary changes experienced benefits, such as increased lean tissue and improved muscular strength and endurance.
When combined with resistance training and weight loss efforts, creatine supplementation promoted fat loss while maintaining lean body mass.
Fitness coach Jacob Zemer noted, “The fact that you can increase lean muscle mass even without exercise is remarkable, especially as we age.”
Cognitive Benefits
Beyond physical improvements, the study highlighted enhancements in memory and cognitive processing tests linked to daily creatine intake. Experts agree that while creatine has clear benefits, it should complement, not replace, regular exercise.
Zemer emphasized, “Supplementation should not be seen as a replacement for regular physical activity.” The maximal benefits emerge when creatine intake complements exercise routines.
Study Limitations
The authors acknowledged several limitations: participants self-selected into exercise or non-exercise groups, introducing potential lifestyle variances; the study spanned only 12 weeks, focusing on healthy adults, which limits insights into long-term or broader applicability.
Considerations for Creatine Use
Before starting creatine supplements, consulting with a healthcare professional is advisable. Recommended dosages differ, with 3 grams typically suggested for women and 5 grams for men; this study employed higher doses. Consistency in taken dosage is key to effectiveness.
The NIH Office of Dietary Supplements considers creatine safe for healthy adults, though some may experience side effects like bloating or stomach discomfort. People with conditions like kidney disease should consult healthcare providers before use.
